An experiment was carried out to study the morphological variability, characters association, correlation and path coefficient analysis of 14 Jamir accessions during the period from January 2007 to March 2008. Significant variations were observed for all the plant characters studied. The accession CJ09 was characterized with the maximum plant height (6.20m), spreading of branch (north-south 4.90 m and east-west 4.87m), base girth (58cm), plant growth (102.76m3), tree volume (24.64m3) and segment length (9.70). The accession CJ15 showed maximum spine length (25.33mm), CJ05 was characterized with high lamina area (14.94cm3). The accession CJ12 showed the highest % fruit set (36.67%). The highest fruit weight (1753.33g), fruit diameter (46cm), rind thickness (2.73cm) was observed in CJ11. The accession CJ09 was characterized with maximum number of segment (15.33) and pulp weight (746.67). Maximum TSS (12.20%) was found in CJ12. The accession CJ09 was characterized with minimum number of seeds (14). Correlation coefficient study indicated that fruit diameter, rind thickness, length of segment and number of segment had positive and highly significant phenotypic association with fruit weight and also genotypic positive association. Percent Fruit set had negative genotypic and phenotypic association with fruit weight. In respect of path analysis, fruit diameter, rind thickness, number of segment, length of segment contributed to maximum phenotypic and genotypic direct effects on fruit weight indicating their importance as selection parameters.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16843 Progress.

For 4 years, `Redchief Delicious' apple [Malus ×sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.] trees were treated with ethephon and/or Accel (6-BA + Gibberellins 4+7) when average fruit diameter was 5.0 to 11.4 mm. Effective thinning was obtained with ethephon at concentrations >500 mg·L-1 and with Accel at concentrations of 100 to 125 mg·L-1. In only 1 year out of 4 did combinations of Accel plus ethephon reduce fruit set more than either material applied alone. Repeat applications of either material alone or in combination reduced fruit set no more than single applications. Fruit weight was negatively related to the number of fruit per tree. After adjusting fruit weight for number of fruit per tree at harvest with analysis of covariance, ethephon did not improve fruit weight at harvest, but Accel improved fruit weight in two of three experiments. The effect of combinations of Accel and ethephon on fruit weight was inconsistent. Chemical names used: 2-chloroethyl phosphonic acid (ethephon); polyothyethylleneploypropanol dihydroxy-propane 2, butoxyethanol (Regulaid); N-(phenylmethyl)-1H-purine-6-amine plus giberrellins A4 + A7 (Accel).

Thirteen exotic genotypes of olive (Olea europaea L.) were studied for the genetic variability, correlation and path coefficient analysis for fruit quality, yield and yield contributing traits at experimental farm of ICAR-CITH, Srinagar during 2009-2013. Maximum variability was recorded for fruit yield and oil content, however, low differ-ences between the phenotypic and genotypic coefficients of variations indicated low environmental influences on the expression of these characters. High heritability coupled with high genetic advance was obtained with fruit yield per plant, acidity, fruit pulp weight, fruit weight and stone weight. Fruit weight (r=0.329), stone weight (r=0.405) and oil content (r=0.841) were the most important traits, which possessed significant positive association with fruit yield per plant. Path coefficient analysis revealed that among the different yield contributing characters oil content (0.875), fruit weight (0.797) followed by acidity (0.501), peroxides value ( 0.199) and fruit length (0.054) influenced fruit yield per plant directly. The direct effects of these characters on fruit yield were found positive and considerably very high.The selection based on fruit weight, stone weight oil content and yield per plant will be effective for enhancing the fruit and oil yieldand making future olive breeding strategies.

Sixty diverse genotypes of mango were selected from the Germplasm Centre of BAU during December 2007–August 2009 to determine the genotypic and phenotypic correlation along with their direct and indirect effects through path coefficients analysis in mango as to estimate the contribution of most important characters towards yield. It appeared that in most of the cases, the genotypic correlation values were higher than their corresponding phenotypic values. This suggests that there were strong inherent relationship between the traits. Percent flowering shoot had significant positive correlation with inflorescence per shoot, percent perfect flower, percent initial fruit set, number of fruits per plant and fruit weight both at phenotypic and genotypic levels. Fruit yield is determined by some components. The residual effects of genetic and phenotypic path analysis were 0.209 and 0.385, respectively, revealed higher genetic variability and also proved lower percent of environmental influence on the selected ten characters. In genotypic path analysis, number of fruits per plant had the highest positive direct effect (0.899) on yield. Higher positive direct effects were also observed for the characters inflorescence per shoot (0.539), percent perfect flower (0.816), and percent initial fruit set (0.292), and fruit weight (0.324). Leaf area, percent flowering shoot, number of fruits per plant, and fruit length showed negative direct effects towards yield. In phenotypic path analysis, except percent flowering, shoot per plant and fruit length and other characters also exhibited similar trend on yield as genotypic path coefficient. In combination with correlation coefficient and path analysis, it was found that number of fruits per plant and percent perfect flower gave significant positive correlation coefficients with yield and also produce the high positive direct effect. Thus, it was clear that plant height, inflorescence per shoot, percent perfect flower, percent initial fruit set per inflorescence, and fruit weight are the major component of fruit yield in mango.

The experiment was conducted during Kharif season 2018 at Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology; Modipuram, Meerut (U.P.) assess the genetic diversity among fifteen genotypes of bottle gourd [Lagenaria siceraria (Mol.) Standl.]. The genetic diversity analysis according to that the formation of five clusters suggesting the presence of wide genetic diversity. The clustering pattern showed that geographical diversity wasn't related to genetic diversity. The analysis of % contribution of assorted characters toward the expression of total genetic divergence showed that the Days to 50% flowering (14.48%) followed Days of fruit set (12.95%), Vine length (m) (11.67%), Number of fruits per plant (10.93%), Number of the primary branches (10.37%), Days to first fruit harvest (10.16%), Average fruit weight (g) (9.44%), Fruit diameter (cm) (6.63%) contributed maximum towards total genetic divergence. Based on the maximum genetic distance. It is advisable to attempt a crossing of the genotype from cluster II (GP-7) with the genotype of cluster I (GP-5), cluster IV (GP-2) and cluster III (GP-1), which may cause to the generation of a broad spectrum of favorable genetic variability for yield improvement in bottle gourd.

Twenty parental genotypes of tomato were planted and observed of yield and yield attributing traits to measure genetic variability, character association and path coefficient analysis. Parent TM 371 ranked first with respect to yield (4.73 kg fruit yield per plant) followed by TM 390. In terms of average fruit weight TM 390 also was better performer. Analysis of variance for each trait showed significant differences among the genotypes. High genotypic and phenotypic coefficients of variation were recorded for fruits per plant, locule number per fruit and fruit yield per plant. Heritability was observed high for flowers per cluster, fruits per plant, fruit weight and fruit length. fruit per plant (52.30), followed by fruit weight (46.32).High heritability associated with high genetic advance was observed for fruits per plant (52.30) and fruit weight (46.32) and flower per cluster (33.50). Selection for such traits might be effective for the fruit yield improvement of tomato. Significant positive genotypic and phenotypic correlation was observed of fruits per plant, fruit weight, fruit diameter and locule number per fruit with fruit yield per plant indicated that selection strategies must be focus on these traits. Fruit diameter showed the highest positive direct effect (3.25) on fruit yield per plant followed by fruits per plant (1.54). Direct selection may be executed considering these traits as the main selection criteria to reduce indirect effect of the other characters during the development of high yielding tomato variety.J.

The effect of different blossom thinners ammonium thiosulfate (ATS) (1%, 2%), Armothin (1.5%), Tergitol-TMN-6 (0.5%, 1%), applied on peach cv. Redhaven at 50–60% full bloom was evaluated in thinning experiments in south-west Slovenia. The photosynthesis inhibitor metamitron (0.05%) applied at 8 mm fruit diameter was evaluated as fruitlet thinner as well. Application of 2% ATS resulted in excessive thinning. The thinning effect of 1% ATS was also too strong in two out of three thinning experiments. The use of 0.05% metamitron did not cause any thinning effect on peach trees and gave similar results as the non-treated control. The effective fruit set reduction and increase of average fruit weight was achieved with 0.5% and 1% Tergitol application. In three-year experiment both Tergitol applications reduced fruit set toward hand thinned level, but the share of fruit from bigger size class was only once enhanced to the level of hand thinned trees. No sign of phytotoxicity was noticed on fruits in all thinner application treatments.

The present experiment was conducted to study the correlation and path coefficient analyses among some morphological and biochemical traits of twenty-three pomegranate genotypes. Results of correlation analysis showed a high, positive and statistically significant (at 0.1% P) correlation between fruit weight and fruit length (r= 0.897), peel weight (r=0.931), fruit volume (r= 0.67), fruit diameter (r=0.554) and total number of arils per fruit (r=0.428). Peel weight exerted direct positive effect as well indirect positive effect on fruit weight through characters like fruit volume, fruit length, total no. of arils per fruit, aril weight and fruit diameter while among the biochemical traits, fruit juiciness exerted maximum positive direct effect on TSS (0.298). The results suggested that these traits could be used for indirect selection of genotypes for higher yield and fruit quality traits will be suitable for cultivation as well as for use in breeding programme.
